7'0 all whom it may concern Be it imoun that. I, Davrux A. Bat-own, a citizen of the United Staten. residing at Worcester. in the county of \Vnrreotrr and Staleufllnssachusettn,hureinwutud t1It(\\' and useful Startling Device for lts-llnglttt'fi Of which the following la a spreithzatiun.

The ohjwt of this invention is to prfiv'nll' a new and hupruvrd starting drviu: for a gas engine h which the rnginr t'ttll have ,quuolrne supplied thereto imlr wiulrntly of the carburetor.

The device has: her-n designed partit-ulnrly for autoamhiles.

The invention is illustrated in the accompanying drawing. referring to which,

Figure l is adiugrainmatie view ehmvin Ilt V invention applied to nu automobile, anll Fig. 2 in an enlarged sectional new showing the construction of my iunn-oveinunt.

Sometimes it. s very dillieult trttittart or crank a gas engine when the same is cold or after it has been utandin for a long time. This is usually occasiuner by failure to ,get the proper amount of gusolene into the byt index-s or to get the gasolene properly vaporized. 'lo ()VttttOtliC this objection I extend a branch pipe-line from the supply and connuut the some to a spray nozzle in the in-tahu pipe, and arrange a forcing tltwllfl'. suuh as a pump in this branch line. A \tllt'e is plan urran ed in this branch line. Then when it. is esired to irilne'm' start the engine. the valve is opener and the pump is worked to force gasolene in the form of a way into the lIl-ttlltt. itpr. As there is uaua l v plenty of air in the vylindora and in-t'uko pipe. the next nrnlth or so of the engine will draw a propi'r iuiuturu into the cylinder and minpress the Sltlllu whereby the. motor will in easily started.

The invention it'll-t further advantages ln'ielllnftul pulnli-il nut- Itch-rump to the drawing and in detail. A

These parts are arranged in the usual way and need no lurther description.

'ltuway my improvement is applied is as tollm\'s:-'lhisupply pipe is topped and extending therefrom is a pipe 11 which con nootu through the f rcing device to a pipe l9, u'hirfh latter i mnnrvterl to a spraying nozzle 13. This nozzle lit in threaded into the intake at tlnpoint where the same tu'unchex out into the two hranrhcs E and i The nozzle is provided with a number of minute openings 130 so as to form a sprayinq nozzle. The nozzle is connected by a coupling 14 to the pipe 12 and a eheeltnut l5 arranged to keep the same rigidly in posit ton.

The forcing device or pump P preferably is arranged on the dash of the automobile and is constructed as fOllOWfiPlk piston ttl which preferably has cup-leathers turned hoth upwardly and downu'urdl is mounted on the 0nd of a piston rod 17 which extends out through a cup screwed on the pump harrrl, whirh piston rod has an operating handle 18 on the end thereof. A T-uoupling I!) is connected b) u serew-threaded nipple to a nut threaded on the bottom of tho pump hurrol. Fir-rowed in the hottoin of this T vouplinu Ill is a nipplu 21 and nr-reu'ed into the end of the nipple is a. plug '22 having a hole through the namev The bottom of the nipple 21 is formed into a valve sent Qtl enaging which is a bull-value 2-1 which is [tlt'trtt'tl to its sent by spring 25 arranged under the plug: 22. A nipple 2G is scre\vthreaded into the T-coupllnp' 1t! and is connurtrd by n ooupliivg 260 with the pipe 12. A plug 2.3 having a hole through the same is act-owed into the nipple 26. The end of the nipptul t is shaped to form n valve-seat 27 engaging whirl] is a hall-valve 29 which is pressed to its neat hv a prina 30 held in plum- In tho ilng "28.

If the ca'rbureter is improper condition, it is usually the best practice to close the valve V as soon as the cylinders are rimed so that the carburetor will he broug i: into action as soon at! possible. In case the carbureter docs n'ot etart easily the valve V may be gradually closed so that the nozzle 13 will.act.as acarbureter; As the valves 94 and 29 open toward the enginothe'action thereof wil suck the gasolenc. out through the nozzle 13. .In case of derangement of the carburetor, by gradually adjusting the valve V th'o'inotor -can be-run b' usin the nozzle 13 as a crude carburetor, t e air ciug drawn in; through air inletpip'e D and thus point indicated, is easy to sometimes-it iepossible' to get out of an ernergencyi .By ocating the. nozzle at the niiirture into the cylinders.
